If you want to view or set Calendar / Agenda acces rights in Microsoft Exchange 2010 SP1 you can do this very easy with powershell. To view the access rights on a users calendar run the following command:

Get-MailboxFolderPermission –Identity **username@organisation.com**:\Agenda (or Calendar dependng on your language settings)


To set access rights for a specific user on another users Calendar run the following command:

Set-MailboxFolderPermission -Identity **username@organisation.com**:\Agenda -AccessRights  Owner –User **Alias** –Confirm (or Calendar dependng on your language settings)
